  <p>Every application has a single root <a href="api/ng/type/$rootScope.Scope">scope</a>.
All other scopes are descendant scopes of the root scope. Scopes provide separation
between the model and the view, via a mechanism for watching the model for changes.
They also provide an event emission/broadcast and subscription facility. See the
<a href="guide/scope">developer guide on scopes</a>.</p>
